Abstract (en)
[origin: EP0823467A2] A masking tape or sheet comprising a substrate comprising a resin (a) comprising a polypropylene as a hard segment and an olefin copolymer as a soft segment, and an adhesive layer formed on one side of said substrate. The masking tape of the present invention can precisely follow the shape of adhesion surfaces having curves, and can provide fine parting lines. In particular, when polypropylene resin (b) is added to the resin (a), the back face of the masking tape becomes smooth and can be adhered easily with fingers, and the tape can be easily cut with a cutter knife. Hence, the use of the masking tape of the present invention leads to an improved efficiency of adhesion work, particularly when the work is manually done. In addition, since the masking tape of the present invention does not contain vinyl chloride in the substrate, the masking tape after use can be incinerated without generating a toxic gas such as chlorine gas.
